How to get a web site to rate in Google or Yahoo
Every one wants to know how to improve their Google ranking. Is there anything you can do to improve your web rankings?
Well one thing is to have a site for a long time ten year old sites rank better. If you don't have a ten year old site you can try getting other people to link to you from their sites.
Computing for tough times
There is a lot of talk about recession and it will no doubt impact on companies IT budgets. How can we save money and still have competitive computing? Many companies have been able to use a mix of open source and proprietary products to achieve outstanding cost savings in their IT operation.

Windows Drops Below 90% Market Share--Firefox Above 20%
by Sam Dean - Dec. 02, 2008
NetApplications is out with a couple of new metrics of market share for operating systems and browsers, and the news is good for open source. Topping their findings, Microsoft Windows' market share has dropped below 90 percent for the first time in its measurements. The share erosion is largely attributed to increased interest in the Mac platform, but Linux is cited as on the rise as well. In addition, for the first time since it launched its metrics, NetApplications' data shows Firefox's market share topping 20 percent.
"Reaching 20 percent worldwide market share is a significant milestone for Firefox and Mozilla," said Mozilla CEO John Lilly. "It's a huge achievement by the global Mozilla community, one that just a few years ago most would have considered impossible."
Firefox's achievement, in particular, is very notable. I clearly remember when Netscape had more than 80 percent browser market share, and when Internet Explorer had 95 percent share. Primarily through its universe of useful extensions, contributed by the community, Firefox proved to be the upstart browser that could. Now, given the fact that extensions are going to come out for Google Chrome, I expect we'll see even more challenges to Internet Explorer from open source browsers.
Enterprise Adoption of Open Source Steams Ahead
by Sam Dean - Dec. 01, 2008
This week brings some interesting new reports on open source adoption in enterprises, providing more evidence that the economic downturn is boosting many open source product categories. BusinessWeek has a big story out on cost-conscious companies turning to open source, ranging from ETrade to the Los Angeles Times. Meanwhile, new survey results illustrate a trend we've written about before: open source moving up the software stack in enterprises.
BusinessWeek's story includes quite a few open source success stories at well-known companies. Among the citations:
Cost-Conscious Companies Turn to Open-Source Software
* Between 2001 and 2002, ETrade was able to cut $13 million a year from its tech spending by switching to open source software.
* H&R Block, Men's Wearhouse, and Shinsei Bank are all now paying customers of SugarCRM, which posted record revenue in the third quarter.
* A September Gartner study finds that about 52 percent of enterprises surveyed are using open-source server software and another 23 percent plan to use it within the next 12 months.
* Office Depot has been steadily moving from IBM and Sun solutions to running Linux on its servers, with about 400 servers running Linux software from Novell.
* The Los Angeles Times has been steadily aggregating collections of images and video using Alfresco's enterprise content management system.
Of course, these are just snapshots, but all of these are also cases where the open source offerings are directly competitive with proprietary alternatives. Meanwhile, in conjunction with the Open World Forum, Bull Services is out with survey results from a commissioned study it did with Forrester Consulting.
The survey results show open source being adopted for productivity tools and core business applications. "An increasing percentage of the surveyed companies... adopted open source CRM (31%), BI (33%) and ERP systems (38%)," the survey found. Seventy percent of survey respondents also said that their positive experiences with open source would cause them to increase its use in the future.
The Bull Services survey is a commissioned one, and I always take results from these with a grain of salt, but the results line up well with findings from Gartner, The 451 Group and others. As we head into 2009, look for open source adoption to increase at the enterprise level.
The world's fastest computers are Linux computers
November 26, 2008 - 8:56 P.M.
Steven J. Vaughan-Nichols
There are fast computers, and then there are Linux fast computers. Every six months, the Top 500 organization announces "its ranked list of general purpose systems that are in common use for high end applications." In other words, supercomputers. And, as has been the case for years now, the fastest of the fast are Linux computers.
As Jay Lyman, an analyst at The 451 Group points out, Linux is only growing stronger in supercomputing. "When considered as the primary OS or part of a mixed-OS supersystem, Linux is now present in 469 of the supercomputer sites, 93.8% of the Top500 list. This represents about 10 more sites than in November 2007, when Linux had presence in 91.8% of the systems. In fact, Linux is the only operating system that managed gains in the November 2008 list. A year ago, Linux was the OS for 84.6% of the top supercomputers. In November 2008, the open source OS was used in 87.8% of the systems. Compare this to Unix, which dropped from 6% to 4.6%, mixed-OS use which dropped from 7.2% to 6.2% and other operating systems, including BSD, Mac OS X and Windows, which were all down this year from the November 2007 list."
Microsoft is proud that a system running Windows HPC Server 2008 took 10th place... behind nine supercomputers running Linux. Even then, this was really more of a stunt than a demonstration that the HPC Server system is ready to compete with the big boys.
You see, there are no Microsoft programming tools to write supercomputer compatible applications. That will come years from now with Visual Studio 2010 and when Microsoft's F# is more than a research project language. In short, Windows HPC isn't ready for prime-time.
In the meantime, the real work is being done on the Linux computers. The number one supercomputer? Once more it's IBM's Linux-powered Roadrunner That's the same supercomputer, which this summer broke supercomputing's sound barrier: a sustained run of more than one petaflop per second or 1.026 quadrillion calculations per second. Beat that Microsoft!
The Roadrunner does have competition now though. The Cray XT Jaguar also recently busted the petaflop wall. The Cray also, of course, runs Linux. In the XT's case, it's running CNL (Compute Node Linux). CNL is based on SUSE Linux.
Needless to say, all the Linux systems do have working parallel-processing languages, like GCC, PGI and PathScale. For now, and the foreseeable future, Linux will not only stay the fastest computers, they'll also be the most useful fast computers.
Ballmer Must Testify In Microsoft Vista Capable Suit
By Damon Poeter, ChannelWeb
9:55 AM EST Mon. Nov. 24, 2008
A federal judge late last week ordered Microsoft (NSDQ:MSFT) CEO Steve Ballmer to testify in the Vista Capable class-action lawsuit, overruling Microsoft's motion to prevent the executive from making a deposition around his knowledge of the marketing campaign leading up to release of the Windows Vista operating system.
Microsoft is being sued for allegedly misleading consumers with its Vista Capable logo campaign in the year prior to the Jan. 30, 2007, release of the Windows Vista operating system. Beginning on April 1, 2006, Vista Capable stickers were placed on PCs by Microsoft's OEM and retail partners—including some older PCs that lacked support for the Windows Device Driver Model (WDDM) required to run certain user interface (UI) features of Vista such as the Aero Glass graphic interface.
Ballmer discusses the Vista Capable campaign in several internal Microsoft e-mails that have been unsealed in batches since the lawsuit was given class-action status by Judge Marsha Pechman of the U.S. District Court for the Western District of Washington at Seattle. Pechman ruled late Friday that Ballmer possessed "unique personal knowledge" of facts relevant to the case and must face questioning.
Court documents unsealed about a week ago added some new details and famous names to the explosive, inside-baseball narrative of a marketing campaign gone terribly wrong. At issue for Ballmer, according to a motion by the plaintiffs, is one-on-one contact made between the Microsoft CEO and other executives at leading high-tech and retail companies, such as Intel CEO Paul Otellini and executives at Best Buy.
Anti Virus News Update!
The Challenge:
The internal computer network is a vital system for the University of Auckland, providing thousands of students and employees with a common information infrastructure that consists of 300 servers and approximately 12,000 desktops. One of the most vulnerable parts of the network is its email gateway, which comprises seven servers and processes up to 1 million emails per day. The email system is prone to a vast number of message-borne threats, ranging from viruses and worms to Trojans and phishing. Such threats are not only potentially harmful to the internal network but could affect the reputation of the entire institution if they infect messages sent from the University. Therefore a decision was made to find an effective antivirus solution which could be integrated with the existing email gateway.
The Solution:
The IT-personnel at the University of Auckland researched the relevant products provided by Sophos, Symantec, McAfee and Kaspersky Lab to determine which of the solutions would be optimal for integrating with the existing email system while providing the highest quality of protection. They found that Kaspersky Anti-Virus for Linux Mail Server had the best malware detection rates, formidable performance and good integration capabilities, as well as supporting a Linux operating system, which was also a key requirement. At the same time, the Kaspersky Lab solution was the most competitively priced , so it held every advantage over the competing products. Implementation of Kaspersky Anti-Virus for Linux Mail Server on the existing email gateway platform went very smoothly – the product was installed and integrated with the existing platform in one week. VNK Technologies, Kaspersky Lab’s experienced partner in New Zealand, provided over-the-phone consultation for the IT staff at the University of Auckland, but no on-site assistance was required during the installation process.

Linux rises to top dog in servers
Stephen Ellis | August 12, 2008
LAST week's LinuxWorld talkfest in San Francisco, which brought together 10,000 vendors and users of the open source operating system, offered yet another indicator of its growing popularity across enterprise IT groups and among developers. The steady march of Linux into ever more central areas of enterprise IT has been visible in the US for about seven or eight years, and has accelerated in the past two. Once consigned to "non-essential" functions such as serving web pages, Linux is increasingly the basis for software stacks that perform critical data centre tasks. This trend is likely to continue, and is a remarkable success story for software once ridiculed as unfit for corporate use, but the focus at LinuxWorld was not the story to date, as much as the future - where Linux and the open source apps that often sit atop it may be headed next.

Computer Virus – Fact, Fiction or Hysteria?
A new headline at PC Magazine calls the Downadup worm an “epidemic”. Other news sources have used similar words and FUD (Fear Uncertainty and Doubt) hype phrases. If you take the “growing exponentially” claims at face value, then throw away your PC right now because we are all doomed. Experts predict this worm will infect at least 8.7 billion PCs by Sunday 25th January.
Mikko Hypponen chief research officer at anti-virus firm F-Secure, says while the purpose of the worm is unclear, its unique "phone home" design, linking back to its point of origin, means it can receive further orders to wreak havoc.He said his company had reverse-engineered its program, which they suspected of originating in Ukraine, and is using the call-back mechanism to monitor an exponential infection rate, despite Microsoft's issuing of a patch to fix the bug."On Tuesday there were 2.5 million, on Wednesday 3.5 million and today [Friday], eight million," he told CNN. "It's getting worse, not better."
What is a computer Virus?
In computers, a virus is a program or programming code that replicates by being copied or initiating its copying to another program, computer boot sector or document. This is not to be confused with other computer programs such as Malware, Adware or Spyware. Viruses can be transmitted as attachments to an e-mail note or in a downloaded file, or be present on a diskette, CD or USB stick/pen. The immediate source of the e-mail note, downloaded file, or diskette you've received is usually unaware that it contains a virus. Some viruses wreak their effect as soon as their code is executed; other viruses lie dormant until circumstances cause their code to be executed by the computer. Some viruses are benign or playful in intent and effect ("Happy Birthday, Ludwig!") and some can be quite harmful, erasing data or causing your hard disk to require reformatting. A virus that replicates itself by resending itself as an e-mail attachment or as part of a network message is known as a worm.
Generally, there are three main classes of viruses:
1) File infectors. Some file infector viruses attach themselves to program files, usually selected .COM or .EXE files. Some can infect any program for which execution is requested, including .SYS, .OVL, .PRG, and .MNU files. When the program is loaded, the virus is loaded as well. Other file infector viruses arrive as wholly-contained programs or scripts sent as an attachment to an e-mail note.
2) System or boot-record infectors. These viruses infect executable code found in certain system areas on a disk. They attach to the DOS boot sector on diskettes or the Master Boot Record on hard disks. A typical scenario (familiar to the author) is to receive a diskette from an innocent source that contains a boot disk virus. When your operating system is running, files on the diskette can be read without triggering the boot disk virus. However, if you leave the diskette in the drive, and then turn the computer off or reload the operating system, the computer will look first in your A drive, find the diskette with its boot disk virus, load it, and make it temporarily impossible to use your hard disk. (Allow several days for recovery.) This is why you should make sure you have a bootable floppy.
3) Macro viruses. These are among the most common viruses, and they tend to do the least damage. Macro viruses infect your Microsoft Word application and typically insert unwanted words or phrases.
The best protection against a virus is to know the origin of each program or file you load into your computer or open from your e-mail program. Since this is difficult, you can buy anti-virus software that can screen e-mail attachments and also check all of your files periodically and remove any viruses that are found. From time to time, you may get an e-mail message warning of a new virus. Unless the warning is from a source you recognize, chances are good that the warning is a virus hoax.
The computer virus, of course, gets its name from the biological virus.
The word itself comes from a Latin word meaning slimy liquid or poison.

Second out-of-cycle update in the last two months is imminent By
Gregg Keizer December 16, 2008 (Computerworld)
Microsoft
Corp. announced today that it will issue an emergency patch
tomorrow to quash a critical Internet
Explorer bug that attackers have been exploiting for more than a
week. The advance warning came less than a week after Microsoft
acknowledged that exploit code had gone public and was being used
by hackers to hijack Windows PCs running IE.
Microsoft will deliver the out-of-cycle patch Wednesday at 1 p.m.
Eastern time via its normal update mechanisms, including Windows
Update, Microsoft Update and Windows
Server Update Services (WSUS).
The update will be pegged "critical," the most serious
ranking in Microsoft's four-step scoring system.
Even as it declared that it would release an emergency fix,
Microsoft continued to downplay the threat. "At this time, we
are aware only of attacks that attempt to use this vulnerability
against Windows Internet Explorer 7," said company spokesman
Christopher
Budd in an e-mail today.
Initially, Microsoft and other security companies believed that
only IE7 was vulnerable to attack, but on review, the company
confirmed
that all versions of its browser, including IE5.01, IE6 and IE8
Beta 2, contain the bug.
Last weekend, Microsoft researchers said that they had seen a
"huge
increase" in attacks, and that some were originating from
legitimate Web sites. Another researcher added that about 6,000
infected sites were serving up exploits that target the IE
vulnerability.
Also today, Microsoft confirmed that attacks could be launched
through Outlook Express, a free e-mail client bundled with Windows
XP. Because Outlook Express renders HTML-based messages using IE's
engine, attackers could exploit the bug by getting users to open or
view malicious messages.
This will be the second out-of-cycle patch from Microsoft in the
last two months. In late October, it issued an emergency
fix for a critical vulnerability in the Windows Server service;
like IE's bug, that one had been actively exploited before Microsoft
was able to come up with a patch.
According to today's advance
notification, Microsoft will provide patches to users of Windows
2000, XP, Vista, Server 2003 and Server 2008 for IE5.01, IE6 and
IE7. A separate patch will apparently be issued tomorrow for IE8 Beta
2, a preview version of Microsoft's next browser that is not
officially on the support list.

15, 2008 (Computerworld) Six-year-old BlueStar Energy Services Inc.
doesn't have the kind of systems-baggage that saddles many older
organizations. Still, the Chicago-based company found itself hindered
by the rigidity of its core systems, which constrained its efforts to
expand its customer base and offer new services.
Those barriers to growth led the company to embark on a bold
effort to replace the bulk of its IT infrastructure -- including
voice, e-mail and financial systems -- with open-source software. The
initiative has been so successful that CEO Guy Morgan attributes much
of the company's recent growth to it.
BlueStar's open-source push has been driven by Tom
Keen, the company's chief technology officer since June 2006.
While evaluating BlueStar's IT architecture and business systems as a
consultant, Keen had seen an opportunity for open-source systems to
provide the company's operations with greater flexibility and
scalability while strengthening its ability to expand into new
markets.
For example, the ERP system, which was written in Macromedia
Inc.'s ColdFusion, suffered from scalability constraints.
BlueStar supplies electricity to customers in Illinois, Maryland and
Washington, D.C., and needs to gather heaps of customer meter data
for billing.
The company was paying third parties for electronic data
interchange (EDI) data feeds, and batch-processing billing runs often
kept BlueStar workers on the job late into the night. The system,
which operated on a Dell
server running Windows 2003, was "pushed out to the edge,"
says Keen, and that restricted the company's ability to expand its
customer base.
"The most pressing concern for me was the rigidity of the
ColdFusion system," says Morgan. "Our business is in a very
fluid regulatory environment. Things change all the time, and our
infrastructure has to adapt to those changes. I felt like we were
constantly putting a Band-Aid on the problem." Even though Morgan recognized the shortcomings of his ERP system,
Keen still had to sell him on the merits of shifting the IT
architecture to an open-source approach. "Guy couldn't
understand why, if open-source technologies are so good, you could
just give it away," says Keen. "He just didn't get it."
To help convince Morgan, Keen had him visit a Web site for
SugarCRM, an open-source CRM system that boasts a number of Fortune
2,000 customers.
"The thing that convinced me is that a number of
well-established companies were adopting [open-source] technologies
early on," says Morgan, noting that open source "started to
make sense to me."
Still, Morgan's confidence had its limits. "He trusted what
we were doing, but his trust had a rope with a noose on the end of
it," says Keen.
In November 2006, Keen and his team began developing a prototype
for a new e-commerce and billing engine that would be part of an
open-source initiative called NextStar. The system would support
BlueStar's customer enrollment, billing, e-commerce, accounting, cash
management and other financial operations.
But BlueStar executives wanted more,
says Keen. They ordered up a comprehensive system that would enable
the company to offer unique services to its customers, such as the
ability to analyze their own energy consumption.
Such services are important to smaller retail electricity
suppliers, says Zarko Sumic, an analyst at Gartner Inc. "[They]
need to develop a portfolio that's equivalent to what the large
players have," he explains.
The project team initially focused on identifying and streamlining
each of the core business processes that would be handled by the
NextStar system, including integration with third-party payment
providers, such as PayPal Inc. and Bank of America Corp., and receipt
of metered data from Commonwealth Edison Co. and other utilities,
says enterprise architect Guillermo
Tantachuco. "The key was to think big, start small and show
early value," he says. For Tantachuco, those efforts began on the day he joined the
company in July 2006. On that day, Morgan informed Tantachuco and
other project team members that they needed to develop a customer
enrollment system that would go live by October. The group developed
a click-through prototype by mid-September and had the
production-ready version completed by the end of the month,
Tantachuco says.
Keen, Tantachuco and other members of the initial four-person
project team used a variety of open-source and commercial
technologies to build out the functionality and support in the
NextStar system. Among them were Project Open's project management
tools.
But the framework for BlueStar's IT architecture was developed
using open-source Java software from SpringSource Inc. The company
selected SpringSource's offering based on its cost, platform
independence and breadth of enterprise-class features, Tantachuco
says. Moreover, the San Mateo, Calif.-based Java vendor had "a
road map of where they'd be in three years, and that mapped with our
plans."
Guy Morgan, CEO, Bluestar Energy Services Most of the Java frameworks that BlueStar evaluated didn't meet
its selection criteria, which included consistent architecture and
design across different layers of systems, flexible and extensible
APIs and security across all architecture layers, says Tantachuco.
SpringSource's modular architecture and design has enabled
BlueStar's IT staffers to develop systems throughout the company's
enterprise architecture, including Web, database, messaging, business
process management and supply chain integration systems, says
Tantachuco.
To aid in the software development, Morgan authorized the creation
of an application development center in Lima, Peru, in January 2007.
BlueStar settled on Lima because there's only a one-hour time
difference between it and Chicago, the city has a sizable population
of IT professionals, and its infrastructure has improved dramatically
in recent years, says Selyn Chavez, a systems architect who works in
the development center there.
Tom Keen, CIO, Bluestar Energy Services Keen set an aggressive timeline for the 25-person project team
(including the first set of Lima-based developers) to build a new IT
infrastructure for the company within a year. The use of the
SpringSource framework kept the project moving briskly, since the
design of the software enabled the project team members to view each
of the system components that their colleagues were working on, says
Keen.
But there were difficulties. "Open source always has some
thorns in it, but so does commercial software," says Keen. One
of the biggest challenges, he says, was simultaneously "rowing,
bailing and building the new boat."
The
IT organization was faced not only with building a new enterprise
platform, but also with maintaining the existing platforms while
building a strategic plan to seamlessly migrate to the new system and
replace third-party vendors, Keen explains. "Not only did we
have to revamp the entire infrastructure, but also revamp all best
practices and standard operating procedures," he says. "This
required extensive planning, coordination and collaboration with our
business team members."
It also required "many early mornings, late evenings, and
long weekends, but the results were well worth the time investment,"
Keen adds.
And that investment ended up being far less than it might have
been. Keen says that the aggregate code count for the NextStar system
is about 40,000 lines -- a fraction of the 5 million to 6 million
lines that one consultant estimated it would take to support
BlueStar's business requirements. BlueStar's investment in open source cost $2.5 million to $3
million, including new Dell servers and the Lima development center,
says Keen.
Pinpointing the return on investment is difficult, because there
are many intangibles, says Morgan, but the numbers are overwhelmingly
positive. For example, he says, "if you look at our revenue
growth from 2002 to 2007 [from $2.4 million to $171.1 million], you
see a big jump toward the end of that, and a lot of that is
attributable to the development of these new systems."
Since Keen and his team delivered the initial version of the
NextStar system in February 2007, operators in BlueStar's
bill-processing center have been able to obtain customer meter data
and generate electronic bills within seven minutes instead of the
eight hours it used to take under the batch-processing system, says
Keen. Those processes have been streamlined, in part, by eliminating
the use of two third-party EDI vendors. By handling those functions
in-house, says Keen, the company is saving $100,000 to $150,000 per
year. And by replacing the ERP system and a host of others, Keen expects
to save $25 million in software license and maintenance fees over the
next five years based on current production loads.
Keen says that though the exact ROI numbers are illusive, the
payback from open source is undeniable. "I tried sitting down
and putting together an ROI analysis," he says, "and it was
surreal."

seems that every year
is supposed to be "the year" for Linux,
but nobody ever manages to define what "the year" really
means. You can find statistics on Linux adoption from a variety of
research firms but all seem skewed to represent whatever agenda that
firm is pushing-whether that is Linux adoption rising, falling, or
stagnating. There is no centralized way of counting Linux adoption because
so
many stories are anecdotal and there are so many channels through
which Linux can be taken up. Rather than rely on unreliable
statistics to make the point that Linux for small businesses in 2008
is a more viable option than ever, we simply need to look at the
continued maturation of SMB-friendly Linux offerings. One of the murkiest challenges that a small business faces
when
even considering a Linux-based software environment is seeing through
the dense range of distributions that make up the Linux ecosystem.
Unlike Windows, which is of course centrally distributed by one
vendor in a limited number of versions, there are many dozens of
Linux-based operating systems. Most Linux distributions are
functionally similar in many ways, but they do differ enough in both
interface and included components that organizations investing time,
money — or both — need to consider their choice. Beyond
functionality, Linux distributions may also differ in available
support channels and/or licensing cost.
Yes,
cost. Although there is a notion that "Linux" equates to
"free" this is not always the case. Many Linux
distributions are indeed free, but commercial solutions such as Red
Hat Enterprise Linux and Novell SUSE come with a price tag. For that
investment, though, you typically receive additional software with
specialized functionality as well as installation and ongoing support
that you might otherwise need to contract from a third-party.
Shortly, we'll look at these options in more detail. Adding to the potentially confusing cost issue is this
scenario:
many major Linux distributions are available in both a fee-based
commercial and a free "community" or "open"
version. Generally speaking, the commercial version of a Linux
distribution will include the most stable (but not necessarily
newest) software packages, may include extra open source or
proprietary software, and will include a support contract. Community distributions, which can be downloaded for free,
offer
much of the same functionality, but may include newer and less well
tested versions of software packages, lack proprietary or closed
source enhancements for enterprise or multimedia, and support amounts
to "you're on your own." Or, if not on your own, reliant
upon volunteer support from the Linux community. When people speak of Linux
they often
make a distinction between desktop and server deployments. Indeed,
Linux has long been a mature presence on servers, first on the
Internet, and in recent years powering corporate and intranet
environments. It has taken longer for Linux to mature on the desktop,
where most users have become accustomed to the Windows experience.
Another factor is that Linux has been dogged by a reputation for an
unfriendly interface. Related Articles The truth is, Linux on the desktop is now mature, and for most
users, any of the Linux distributions we look at for small businesses
would require very little adaptation. Plus, desktop Linux users are
protected from the malware threats that proliferate on Windows
machines. The main limitation that remains for Linux on the desktop
is application availability. For a small business that relies on
particular applications that are available only for Windows-such as
Quicken or Outlook-it may be more difficult to justify a Linux-based
desktop. Some commercial Linux distributions are licensed in either
server
or desktop versions. Typically, you can use a server version as a
desktop, although it may not include as many client applications, and
the vendor may not support client applications you add. Likewise,
many desktop distributions also include server software, particularly
for common server functions such as file sharing, databases, and Web
applications. In other words, the boundaries between server and
desktop Linux can be blurry, and may be defined more by licensing
fees and support terms than significant technical differences. When you boil down the myriad choices in Linux land, six
distributions stand out as the most attractive for the small business
whether you are looking at desktop or server solutions. Red
Hat
Enterprise Linux 5 For server use, RHEL supports a wide range of processing
platforms
from single CPU machines to SMP and clustered configurations. Network
storage is available with support for protocols like Autofs, FS-Cache
and iSCSI. And Microsoft integration is enhanced with ActiveDirectory
support and Microsoft file and printer sharing. In a desktop environment, RHEL uses Gnome, an interface that
is
easy to learn for both Windows and Mac users. RHEL 5's most
significant new feature is its integration with Xen virtualization,
meaning that it includes out-of-the-box support for running
virtualized OS environments, which may include additional or earlier
Red Hat releases, other Linux distributions, or even Windows. Because the components in this commercial Linux distribution
are
well-tested, RHEL is certified for 600 hardware configurations, and
can run over 1000 certified applications. A Basic license costs $349
per year and includes Web-based support, while a $799 Standard
license buys 12x5 phone support. Fedora
9 Unlike RHEL, Fedora is developed on a more rapid timeline —
six-month releases versus eighteen-month releases for RHEL. This
means that the software versions of Fedora components have had less
time to be tested. The idea is that Fedora is a test bed for software
that may eventually find its way into RHEL, should it prove useful
and stable enough. Likewise, Red Hat provides no formal support for
Fedora, although there are thriving Web communities you can use as a
resource. For a particular small business, there is not necessarily one
right choice between
RHEL and Fedora. As a general guide, a very small business
with
technical aptitude but a limited budget might be drawn toward Fedora,
while a larger small business with a more complex operation could
benefit from the proven stability and support behind RHEL. Novell
SUSE Linux 10
For most practical purposes, SLES and RHEL provide very
similar
feature sets. SLES includes Novell's AppArmor security
(application-specific permissions) and their highly praised YaST
tool, a kind of all-in-one system control panel and installed
software manager. Like RHEL, SLES includes integrated virtualization
using Xen. On the desktop, SLED includes both Gnome and KDE
interfaces. While Gnome is typically considered more accessible for
the average user or Windows refugee, KDE is considered by many to be
a more powerful desktop and is often preferred by enthusiasts. To drive home the point of how closely matched these two Linux
giants are, the entry-level licenses for SUSE are priced at $349/year
and $799/year — exactly the same as RHEL, with equivalent support
terms. OpenSUSE
11
For example, SLED includes KDE version 3.3, an older but
mature
desktop. OpenSUSE includes KDE 4, a major upgrade with a much
"sexier" desktop environment. But KDE 4 is still under
active development and, while it will "mostly" work, issues
may arise and there is no formal support to rely on. CentOS
5 Put another way, a rebuild is often like a clone, and in the
open
source software world is perfectly legal. CentOS ("Community
ENTerprise Operating System") is just such a rebuild, a
re-packaging of RHEL 5. Of course, while Red Hat provides formal
support through license fees for RHEL 5, no such support is offered
for CentOS. In that case, how is CentOS different from Fedora? Because
CentOS
does not contain the "bleeding edge" components of Fedora,
but the stable and well-tested components in RHEL 5. If you're new to
open source, all this might sound a little shady, but in fact CentOS
is one of the more popular Linux distributions. For the small
business, CentOS offers a budget-conscious alternative to the
stability risks of Fedora without paying for the formal support of
RHEL 5.
Ubuntu
8.04 Indeed, Ubuntu has developed a reputation not unlike the Mac.
It
is adored by desktop users, but without a strong presence in server
racks. The reality, however, is somewhat different. Ubuntu (and Macs)
do have a place on the server, although not so often seen in large
scale enterprise back-ends. For the small business, the Ubuntu Linux offers several
attractive
benefits. One, it is free to download and use in any scenario you
want. You can optionally pay for a support subscription ($250
desktop/$750 server, annually). Unlike Red Hat and SUSE, foregoing
paid support does not mean having to use a separate community edition
with different software versions. With Ubuntu, you are always using
the vendor-sponsored-and-tested platform. Because Ubuntu provides a very strong desktop experience with
support for a wide range of consumer hardware, it is easy to deploy
in a variety of environments. At the same time, many small businesses
will be adequately served by Ubuntu's typical range of server
software, from Windows-compatible file and print sharing to Web
serving and database support. More ambitious server packages can be
installed in Ubuntu, although it may take a little more work on your
end compared to turnkey enterprise distributions. Related Articles Finally, Ubuntu is particularly well-supported by its user
community. Even without paid support, answers to almost every
conceivable issue are available at Ubuntu Web forums, which are often
oriented toward the non-expert Linux user. In short, would Ubuntu Linux be the top choice for an
enterprise
running a 2,000 CPU production backend? Probably not. But for a small
business with modest needs, Ubuntu can be a free, friendly,
minimum-fuss solution. These six Linux distributions are just the tip of the iceberg
because Linux is a deep and vast ocean. In practice, though, the
majority of Linux deployments, particularly in business environments,
involve one of these six platforms because they address the major mix
of needs between form, function and pricing. Linux is all about
choice, which also means you have the choice whether to explore Linux
distributions in more depth — or not. Aaron Weiss a technology writer, screenwriter and Web

Corp. warned Saturday of a "huge increase" in attacks
exploiting a critical unpatched vulnerability in Internet
Explorer (IE) and said some originated from hacked pornography
sites. Other researchers confirmed that attacks were increasingly coming
from compromised Web sites.
Microsoft noted the upswing in attacks on its Malware
Protection Center blog late Saturday. "The trend for now is
going upwards," said researchers Ziv Mador and Tareq Saade on
the blog. "We saw a huge increase in the number of reports today
compared to yesterday."
Hackers have been exploiting a data binding bug in IE for more
than a week, according to researchers who first noted in-the-wild
attack code on Chinese
servers. The vulnerability, which exists
in all versions of the Microsoft browser, including IE5.01, IE6,
IE7 and IE8 Beta 2, has so far been exploited only by attack code
that targets IE7, the most widely-used edition.
Mador and Saade said that attacks are increasingly being launched
from legitimate Web sites. "Some legitimate Web sites were
maliciously modified to include the exploits," the two said. A
popular Taiwanese search engine and a Hong Kong-based pornography
site were among the sites that were hacked, then set up to attack
visitors running IE.
Researchers at Trend
Micro Inc. also reported a big increase in hacked sites serving
exploits aimed at the new IE bug. On Saturday, the security firm
estimated that about 6,000 sites have been infected so far, noting
that the count was "quickly increasing in number."
As in previous, large-scale attacks based on legitimate Web sites,
this one involves hackers who execute SQL injection attacks to first
compromise the sites. In a SQL injection attack, hackers exploit
vulnerabilities in Web applications that rely on a back-end database,
which then gives them a way to add and run malicious code, usually
rogue JavaScript, against any browser.
Microsoft acknowledged that attacks have become a significant
problem. "Based on our stats, since the vulnerability has gone
public, roughly 0.2% of users worldwide may have been exposed to Web
sites containing exploits of this latest vulnerability," Mador
and Saade said. "That percentage may seem low. However, it still
means that a significant number of users have been affected."
The move to legitimate, but hacked, sites is a change in tactics.
As recently as Thursday, attacks were coming only from malicious
sites, most of them in China. Even then, however, Microsoft had
warned that hackers would probably expand the scope of their attacks
by compromising valid sites. In related news, Microsoft said it was working on a patch for IE,
although the company has still not said when it would issue the
update. Some researchers expect the vendor to release a fix outside
its normal monthly schedule; the next security updates aren't due
until Jan. 9, 2009. Microsoft also revised its security
advisory for a third time on Saturday, adding more information
about the recommended
actions users should take until a patch is available. The company
has offered up a total of nine different work-arounds for IE users,
several of which require editing of the Windows registry, a chore
most users assiduously avoid. DirectX 11 Confirmed For Microsoft Windows 7 German computer magazine PC Games Hardware received information from Ben Basaric, Product Marketing Manager Windows, that Windows 7 will ship with DirectX 11. He also confirmed that DirectX 11 will also be released for Windows Vista with the most likely scenario that DirectX 11 will be shipped as part of Windows Vista Service Pack 2. Windows 7 News Senior Vice President Bill Veghte stated that Windows 7 will not have the kind of compatibility issues with Vista that Vista has with previous versions “You've let us know you don't want to face the kinds of incompatibility challenges with the next version of Windows you might have experienced early with Windows Vista. As a result, our approach with Windows 7 is to build off the same core architecture as Windows Vista so the investments you and our partners have made in Windows Vista will continue to pay off with Windows 7. Our goal is to ensure the migration process from Windows Vista to Windows 7 is straightforward.” Speaking about Windows 7 on 16 October 2008, Microsoft CEO Steve Ballmer confirmed compatibility between Vista and Windows 7 “Our next release of Windows will be compatible with Vista. The key is let’s get on with it. We’ll be ready when you want to deploy Windows 7.” Ballmer also confirmed the relationship between Vista and Windows 7, indicating that Windows 7 will be an improved version of Vista

Six Reasons Why Linux Is Right for
Small Business
By Aaron Weiss
Clearing the Fog
Desktop and Server
The Linux Six: Top Solutions for Small Business
Despite having "enterprise"
in its name, RHEL is popular with many small- and mid-sized
businesses, as well. Red Hat is perhaps the most established name
among commercial Linux vendors, having been founded in 1995.
In
addition to their Enterprise Linux release, Red Hat also sponsors
Fedora, the community edition oriented toward developers and
enthusiasts. Fedora contains many of the same components as RHEL 5,
but you can download and install it for free — no licenses to buy.
Red Hat's biggest competitor is Novell SUSE, a
commercial/community Linux distribution that is developed according
to the same model as RHEL/Fedora. Also like RHEL, SUSE is divided
into a server and a desktop product, known as SLES (SUSE Linux
Enterprise Server) and SLED (SUSE Linux Enterprise Desktop). Again,
the server product does include a desktop environment and can be used
that way, although it includes fewer client applications than the
full-blown SLED.
Whereas RHEL has its free Fedora counterpart, SUSE has
OpenSUSE. The model here is the same — OpenSUSE is a
Novell-sponsored community distribution. Like Fedora, it is released
on a much faster cycle than its commercial counterpart, and therefore
contains "bleeding edge" software that provides the latest
features at the possible cost of less testing for stability and
compatibility.
In the remix culture of Linux, there is another twist
on the commercial vs. community paradigm: the "rebuild." In
this case, a third-party collects the open source software that makes
up a more well-known Linux distribution, like Red Hat Enterprise
Linux, and re-packages it into a separate distribution.
Some may raise an eyebrow at seeing Ubuntu listed
among business-oriented Linux platforms. By its own design, Ubuntu
&#
151a South African concept for "being human" — has been
developed as an accessible, end-user-friendly Linux known for being
warm and fuzzy.

With the clanging of Windows XP’s death knell ringing loud and clear in the lead up to its June 30 cutoff, Microsoft today has released the final Windows XP Service Pack to computer builders and volume licensing customers.
ItNews
Hot on the heels of a recent hack in which 10,000 sites were compromised, researchers have disclosed a new large-scale attack. Researchers at McAfee estimated that the attack has been active for roughly one week, and in that time frame has managed to place itself on roughly 200,000 web pages.ItNews
Tony Fadell, the senior vice president in charge of Apple’s iPod division, is leaving the company to be replaced by Mark Papermaster, a former Big Blue executive who is being sued by IBM over a non-compete clause.
The move (statement), first reported by the Wall Street Journal, marks the departure of one of the executives behind Apple’s transformation into an entertainment and mobile handset company. Fadell had his fingerprints on two of Apple’s big hits: The iPod and the iPhone. You could argue that those two products transformed Apple into what it is today.Zdnet.com
RUPERT Murdoch is clearly captivated by that strange beast Google,
which emerged from a garage in suburban Menlo Park in California to in
barely half-a-dozen years colonise just about every computer screen in
the world.
He sees it as bringing down the Microsoft monolith, which has ruled the
computer world so completely and so ruthlessly for so many years.
Does Microsoft face competition, I ask? Absolutely! he responds with
emphasis. Microsoft's dominance has gone. Google is the dominant player
today, he thunders.

Are you wasting money and resources by having equipment that is too old?
Compact fluorescent performance decreases over time.
While a filament does exist in these lamps, the real work of making light is done by the gas discharge. The light bulb does not just “burn out,” but instead slowly degrades over time putting out less and less light. Because this decay is slow it often goes unnoticed by users until the performance is well below acceptable. The same thing applies to computer monitors. Staff are often staring a monitors that are several years old. This is not only a work place safety issue as it effects the well being of the user but it lowers efficiency of the workers as they strain to comprehend quickly and accurately exactly what they are reading. Given the relative low cost of these devices there is little excuse for not having you monitors less than three years old.
"Whilst it is not exactly the same thing you do get a similar loss of efficiency with windows based computers over time. As the computer gets used more and more and as programs are added and removed there is an apparent loss of performance."
This loss of performance also effects the output of the user so it is also a wise idea to keep the life of your computers relative low if you want to get the best out of your staff. Just as running old fluorescent lamps is a false economy so is running old computer equipment.
